1. ### Physic A football of mass 0.420 kg is thrown 60.0m by a quarterback who imparts to it an initial velocity at 45 degrees above the horizontal?

First find the square of the velocity (there's a formula for that), then find the work done which will lead you to the force. range x = V²sin(2Θ) / g 60.0 m = V² * sin90º / 9.8m/s² V² = 588 m²/s² Then the QB gave...

2. ### An MSU linebacker of mass 116.0 kg sacks a UM quarterback of mass 79.0 kg. Just after they collide, they are?

Use the principle of conservation of momentum to solve this problem Total momentum before collision = Total momentum after collision Before, We have momentum of line backer = M1 V1 = 116 V1 Momentum of quarter back is zero (He...

3. ### motion problem(challenge)???

Doug can catch the ball while it is rising, or at its maximum height or while it is falling depending on the initial velocity.But since douglas is at the tight end he should catch the ball while it is rising. Here we need to know the...

5. ### grade 11 physics question?

Use the trajectory eqn: y = h + x·tanΘ - g·x² / (2v²·cos²Θ) 2m = 1.8m + xtan35º - 9.8m/s² * x² / (2(12m/s)² * cos²35º) 0 = -0.2 + 0.7x - 0.0507x² quadratic in x, solutions at x = 0.29...

6. ### HELP with physics problem?

There is a simple formula for this: range x = V²sin(2Θ) / g Here, 177 m = V² * sin67.2º / 9.8m/s² which solves to V = 43.4 m/s Seems super-exceptional to me. (That's almost two football fields, btw...
